The average life span of a snail is approximately 10 to 15 years in captivity. However, it is believed that some species can live up to 25 years this way. In the wild however, lifespan varies from species to species, but range from 2-3 in some cases to 5-7 for other kinds of land snails.
In theory snails can go a very long time (months and months maybe much longer) without food as long as they are dormant (but i wouldn't consider it as a going away option). With the correct long lasting foods and setups mine are happy to be left for up to two weeks, they could probably do longer but i am not happy to do that.
